War Thunder .ddsx image format

[InnerCircle]

Hello everyone!

I have a Problem regarding .ddsx Files. I´m creating skins for the F2P Game War Thunder. Although the game has an built-in Feature to create Skin Templates for Planes and Tanks (supports .dds/png./tga/.jpg), but some of those templates are missing elements like Normalmaps, additional Textures, etc...

A Guy from the WT Community made a tool to open/extract the content for most of the game archives. Almost every image inside those are in .ddsx though my attempts at finding a solution how to convert them have failed so far.

I´ve attached an example file so i would be very grateful if smeone could help me out here

It's compressed by lzma.
Here's decompressed data.It's headerless dds.

Thank you

I found a topic on this forum which seems kinda related since this Game uses the same Engine: viewtopic.php?p=30696#p30696

then I looked at the dds files in a hex editor and just pasted a valid dds header over it which was dxt5 and no mip maps.

Could you tell me how to do this? I know I´m a total noob with Hex Editing and stuff

Anyone else who might help me please?

to do it through hex editing you would copy the header from another dds file and paste it at the beginning of your uncompressed headerless file.

Example DXT5 header with no mipmaps

If you don't want to mess with hex editing you could open the uncompressed file in TextureFinder with correct settings and save it as *.bmp then convert it to *.dds.

I think what he means is how to unpack .ddsx textures - I've tried it myself, with QuickBMS and different variations of LZMA with different offsets, but none of them worked.
